Definitions

  • An object of the present invention is to provide an improved coupling which can readily be attached to the pipe or hose so as to make a perfectly tight joint.
  • a rigid holding ring of which the inside diameter is substantially equal to the external diameter of the tube, is displaced axially along the end of the pipe when the two coupling members are coupled together, so as to compress the pipe radially against the tubular member and so obtain a perfectly tight joint.
  • the external diameter of the end of the tubular member which is inserted in the flexible pipe may be slightly greater than the internal diameter of the tube, so that, after insertion, the end of the tube is flared outwardly to a slight extent, or it may be substantially equal to the internal diameter of the pipe in whichcase a deformable sleeve is fitted over the'outside of the end of the flexible pipe.
  • the coupling members may suitably consist of an externally threaded bored or tubular member and a nut which screws thereon by which the axial displacement of the holding ring is effected.
  • the tubular member can be provided with hollows, or indentations, preferably arranged in checkerboard fashion, so that, when the holding ring is displaced axially, some of the material of which the pipe is made is forced radially into these cavities, and firmly anchored therein.
  • the inner edge of the ring at the end facing the end of the pipe is rounded. This rounding also facilitates the axial displacement of the holding ring.
  • the tubular member may be provided with a collar against which the end of the pipe bears, while the end of the tubular member which is not inserted in the pipe may be enlarged or in the form of a connecting flange which fits in the mouth of one of the coupling members.
  • One of the coupling members for example the nut, can serve at one and the same time for fixing the end of the pipe on the tubular member by displacing the holding ring axially or by deforming the metallic sleeve, and, through the agency of the collar, for pressing the enlarged or flanged end of the tubular member against the mouth of the other coupling member.
  • Fig. 2 is a similar section after the coupling members have been tightened
  • Figs. 3 and 4 are similar sections through a slightly modified form of construction.
  • a represents the flexible pipe
  • b the holding ring which moves axially and of which the inside diameter is substantially the same as the outside diameter of the pipe a.
  • the holding ring I is preferably made of metal and undeformable.
  • the reference 0 designates a tubular member of which one end is inserted in the pipe (1, while d is a nut which screws on to the threaded coupling member e.
  • the ring D is moved axially along the pipe a.
  • the threaded member e is bored 'to a diameter substantially the same as the inside diameter of the pipe a and its mouth e1 is widened to form a seating for the enlarged end 03 of the member c.
  • the end of the tubular member 0 which is inserted in the pipe a is provided with cavities or recesses, preferably arranged in checkerboard fashion i. e. in a grid-like pattern, into which the material of which the pipe is made is forced radially when the holding ring b is displaced axially when the nut d is screw-ed on the threaded member e.
  • the end of the pipe a bears against a collar 02 on the tubular member 0 which prevents the pipe from being moved axially when the holding ring b is displaced in the same direction, so that the material of the pipe is forced into the cavities in the tubular member 0.
  • the enlarged end 50 c3 of the tubular member 0 may be of spherical, conical, or of any other suitable shape, so that it forms a tight joint with the widened mouth e1 when the nut is screwed on the member e.
  • the end of the holding ring D facing the u threaded member c has a collar bi while the edge of its orifice is rounded. aflording a wedging portion.
  • the base d1 of the nut bears against the collar D1 of the holding ring D so that, when the nut d is tightened, the holding ring D is movedaxially along the pipe a.
  • the cylindrical part of the holding ring D must be passed through the opening provided in the basedr of the nut d as shown in the drawing.
  • the tubular member c is inserted in the mouth of the pipe a, thus flaring'it slightly.
  • the coupling is effected by means of one and the same tightening device namely the nut d, in two operations.
  • the nut presses the pipe a on to the tubular mem ber c.
  • the tubular block c to which the pipe has been firmly connected is pressed into the mouth e1 of the threaded shoulder e.
  • any other suitable coupling members could be used instead of those illustrated.
  • the enlarged end es of the tubular member is spherical.
  • the coacting parts of the tubular member 0 and the coupling part e could be of any other suitable form.
  • Figs. 3 and 4 show another form of coupling which is similar to that described with reference to Figs. 1 and 2. 1
  • the pipe a is covered with a metal braid a1, and for this reason lends itself badly to flaring.
  • the outside diameter of the tubular member 0 must be substantially equal to the inside diameter of the pipe at, and not slightly greater as in Figs. 1 and 2.
  • the coupling is effected in the following manner.
  • the end of the pipe is provided with a deformable metallic sleeve ,f of which the inside diameter is substantially equal to the outside diameter of the pipe a.
  • the holding ring b forces the sleeve to contract radially, that is to say, to decrease in diameter, the effect of which is to cause the material of the pipe to become anchored in the cavities in the tubular block 0, as previously described.
  • the sleeve I should be sufliciently deformable vto be able,to .contract radially. It is preferably made of metal, but "may be made of other material, forv instance suitable plastic material, provided it is capable of contracting radially under the action'fof thedisplacement of the holding ring 1;.
  • the coupling can be disconnected and reassembled at will. Should it be desired to disconnect the pipe, the holding ring b must be withdrawn axially so as to permit the end of thepipe a to be freed. In some cases, the couplingpart e and the tubular member c can be made in one piece. Then, the end of the pipe 0 and the sleeve f abut directly against the coupling member e.
  • a pipe coupling in accordance with claim -1 wherein the outer surface of the cylindrical por-l tion of the tubular member is provided with a plurality of spaced cell-like cavities disposed in a v grid-like pattern into which the material of the pipe is pressed.
